I'll be honest, the whole Paleo + Zone thing isn't working out real well. I've fallen back to just eating Whole30 style and not worrying about my Protein/Carb/Fat ratio at meal times. Many of the dishes that I prepare are filled with veggies, good proteins and good fats to begin with.
Since the challenge at our box is 9 weeks long, we thought about doing the Whole30 for the entire 9 weeks. Then I decided that I was NOT going to miss out on trying new paleo treats for my birthday (mid-February). So... I plan to do a Whole45, then take a 5 day "break" (allowing for paleo birthday treats and GF alcohol) followed by another Whole17. That will get us to the end of the nutrition challenge! All with the intention of reducing my body fat percentage.
Here's what this is gonna look like:
Jan 1 thru Feb 15 (until the evening) - Whole30
Feb 15 (evening) thru Feb 19 (my birthday) - Paleo
Feb 20 thru March 9 - Whole30
After that, it's back to paleo!
After all that, I still plan to do a few more Whole30s throughout the year. Possibly in May next. I started a Facebook Group for those doing the Whole30 in January with me, but changed it to include all of 2013, so join in anytime! There's plenty of support and experience on that page!
